PROCEFQS OF TR-EATING- LINT.

Application filed. May 10, 1911.

To all whom it may concern Be it known that 1, JAMES E. Cranes- MAN, a citizen of the United States of America, and a resident of South Orange, county of Essex, and State of New Jersey, have invented certain new and useful lmprovements in Processes of Treating Lint, of which the following is a specification, reference being had to -the accompanying drawings, forming a part thereof.

My invention relates to a novel method of treating lint to clean and separate the fibers. Cotton lint, particularly as it is received from a roller cotton gin, is in a somewhat matted condition and carries with it a certain percentage of dirt, dust, leafy trash, etc.

The object of the present invention is to improve the condition of the lint by opening out and separating the fibers, and cleaning them, to the end that the final product may be in a clean, homogeneous, and fluffy condition.

In a copending application, serially numbered 604L320, filed January 24:, 1911, T have disclosed and claimed a process in which the lint is moved by air currents past a plurality of fingers which project obliquely in the direction of the flow of the currents, whereby thelint is arrested from time to time by the fingers while the air is acting upon the same, and by which the fibers are opened out and changed from their matted to a more fiufly condition, and in being so opened out are cleaned in the sense that dirt, dust, leafy trash, etc., is removed therefrom.

My present invention relates to such a process, and consists essentially in varying the velocity of the air currents while the lint is being treated so that while the lint when in its matted condition is thrown with considerable force against the fingers, the force with which it is so thrown is gradually de creased as the fibers are opened out. By this means a maximum of efiiciency is obtained, for it will be well understood that while a greater force should be employed while the fibers are closely matted, a less force is desirable after the fibers have been opened out. Any suitable form of appa- Specifieation of Letters Patent.

Serial No. 626,222.

ratus may be employed for carrying out such process, and I refer to a copending application serially numbered 626,221, filed upon even date herewith for one such form of apparatus.

The drawing herewith represents in some what diagrammatic form such an apparatus, in which a lint flue 5 contains a channel 6 formed in a plurality of horizontal superposed sections whose cross-sectional area progressively increases from the section which first receives the material to be treated, to the section from which it is finally discharged. A blower 7 draws lint from a gin 8 or other source of supply, and delivers it to the channel 6. As the crosssectional area of the channel 6 increases from one end to the other it follows that the speed of the air currents therethrough will decrease in proportion thereto. The channel 6 is provided with fingers 9 throughout the length thereof, against which the lint will be thrown, and by which the lint will be temporarily arrested from time to time in its travel through the flue. As the velocity of the air currents decreases in the travel of the air through the channel, it follows that the severity of the action of the fingers upon the lint will relatively decrease as the lint passes from one end of the channel to the other.

What I claim is:

l. The herein described process of treating lint which consists in moving it by air currents arranged to flow in a zigzag path, temporarily retarding the advance and onpositely changing the direction of movement of particles of said lint relative to said currents at fixed intervals along its path of travel, whereby the air currents are caused to blow through said lint, subjecting said particles of lint to a combing action at the end of said fixed intervals of retarded advance and cleaning the lint at the'turns in said zigzag air current path.

2. The herein described process of treating lint which consists in moving it by air currents arranged to flow in a zigzag path, temporarily retarding the advance and oppositely changing the direction of movement of particles of said lint relative to said currents at fixed intervals along its path of reducing the velocity of the air currents in travel, whereby the air currents are caused the advance thereof.

to blow through said lint, sub'eotin said a particles of lint to a combing a ction at the JAMIJS CHEESMAN' 5 end of said fixed intervals of retarded ad- Witnesses:
